CSS Swapping a logo image when a user hovers over a link?

[mistercrabb]

Hi,
I was just wondering, is it possible to change an image if a user hovers over a different link?
I want my logo to change when the user hovers over a button on my nav-bar.
I know I have seen this before, in tutorial form, and I was sure it was done using CSS..

I don't really want to start using Javascript yet, so if it's not possible with CSS then that's fine I have a backup plan
